Grado, Friuli-Venezia Giulia in the context of "Province of Gorizia"

The Patriarchate of Aquileia was an episcopal see and ecclesiastical province in northeastern Italy, originally centered in the ancient city of Aquileia, situated near the northern coast of the Adriatic Sea. It emerged in the 4th century as a metropolitan province, with jurisdiction over the Italian region of Venetia et Histria. In the second half of the 6th century, metropolitan bishops of Aquileia started to use the patriarchal title. Their residence was moved to Grado in 568, after the Lombard conquest of Aquileia. In 606, an internal schism occurred, and since that time there were two rival lines of Aquileian patriarchs: one in New Aquileia (Grado) with jurisdiction over the Byzantine-controlled coastal regions, and the other in Old Aquileia (later moved to Cormons). The first line (Grado) continued until 1451, while the second line (Cormons, later Cividale, and then Udine) continued until 1751. Patriarchs of the second line were also feudal lords of the Patriarchal State of Aquileia. A number of Aquileian church councils were held during the late antiquity and throughout the middle ages. Today, it is a titular archiepiscopal see.

Portorož (pronounced [pɔɾtɔˈɾóːʃ] ; Italian: Portorose) is a Slovenian Adriatic seaside resort and spa settlement located in the Municipality of Piran in southwestern Slovenia. Its modern development began in the late 19th century with the vogue for the first health resorts. In the early 20th century Portorož became one of the grandest seaside resorts in the Adriatic, along with Opatija, Lido and Grado, then as part of the Austrian Littoral. It is now one of Slovenia's major tourist areas. Located in the centre is the Palace Hotel, once one of the most important resorts for the Austro-Hungarian monarchy, and currently one of the finest hotels between Venice and Dubrovnik.

The settlement and its surrounding areas are served by Portorož International Airport which is located in the nearby village of Sečovlje.

The Patriarchate of Grado, also known as the Patriarchate of New Aquileia, was an episcopal see and ecclesiastical province in northeastern Italy, centered in Grado, on the northern coasts of the Adriatic Sea. It was created as a result of an internal schism within the ancient Patriarchate of Aquileia. In 568, after the Lombard conquest of Aquileia, patriarch Paulinus left the city and fled to the minor coastal, but better protected town of Grado, that still remained under the Byzantine rule. First patriarchs who resided in Grado continued to exercise their jurisdiction over bishops in Lombard-held parts of the province, but at the very beginning of the 7th century a schism occurred, when bishops in Lombard regions elected their separate patriarch (Ioannes), who took residence in the old Aquileia, thus becoming rival to Candidianus of Grado. From that time, the region was divided between two distinctive jurisdictions: the Patriarchate of Old Aquileia in Lombard-held lands, and the Patriarchate of New Aquileia, with residence in Grado and jurisdiction over Byzantine possessions in the northern Adriatic (including Venice and Istria).

Initially, the patriarchs in Grado continued to claim the title of Patriarch of Aquileia, but in the early 700s it was gradually dropped and then officially changed to Patriarch of Grado. Throughout their history, the patriarchs of Grado, with the support of Venice and the Byzantines, fought military, politically, and ecclesiastically the patriarchs of old Aquileia, who were supported by the Lombards, and later the Carolingians and the Holy Roman Emperors.

The Patriarchate of Old Aquileia was created at the beginning of the 7th century, as a result of an internal schism within the Patriarchate of Aquileia. It was centered in the old Aquileia, that was held by the Lombards, while the rival Patriarchate of New Aquileia in Grado was under the Byzantine rule. Residence of the patriarchs of Old Aquileia was later moved, first to the city of Cormons, then to Cividale, and finally to Udine. Since 1077, patriarchs of Old Aquileia were also temporal lords of the Patriarchal State of Aquileia, that was annexed by the Venetian Republic in the first half of the 15th century, while the Patriarchate of Old Aquileia continued to exist as an ecclesiastical institution until 1751, when it was also abolished.
